wanarace Mar 27th, 00, 3:23 PM Has anyone tried the RPM Air Gap? Does the "gap" acutally help the air charge stay cooler? I cannot imagine there beeing much of difference between the RPM Air Gap and the regular RPM. Thanks for any help ------------------ 66 327 Malibu L6571SS Mar 27th, 00, 3:37 PM Probably just a gimick ------------------ JT 71 SS Vortec 355 www.angelfire.com/co/KellyMotorsports (http://www.angelfire.com/co/KellyMotorsports) racer1320 Mar 27th, 00, 3:49 PM Have it on my 467 BB. Back to back swap with an RPM, no quicker or faster. It "looks" faster though but the casting is rough. 69bigblock Mar 27th, 00, 4:05 PM Would the rpm air gap help over a performer 2.0 on a 454? ------------------ Frank 69-454-456 Gold Member # 216 racer1320 Mar 27th, 00, 5:11 PM Depends on a number of things like cam, compression, converter and gear. In a mild motor it's not worth the money. SS 396 Mar 27th, 00, 5:49 PM In theory, the air gap would help to make power. But in a real world situation it makes little, if any, differance.+ICE- [This message has been edited by SS 396 (edited 03-27-2000).] BLURAT Mar 27th, 00, 9:03 PM Don't know from personal experience,BUT a TC member is selling his freshly painted stock 69SS Chevelle hood because it won't fit over his recently "installated" new airgap on the rat.FYI-Shawn ------------------ 69ChevConv Mar 28th, 00, 9:34 AM WHAT!!!!!! I'm almost done with a frame off on my 69 SS. I installed a RPM AIR GAP manifold, heads, & cam. My hood is at the bodyshop, WHAT DO YOU MEAN IT NOW WONT FIT ON MY CAR http://www.chevelles.com/forum/eek.gif with a air gap manifold!!! Can anyone else confirm this is true. Even with a low profile air cleaner?? I E-mailed the person with the hood for sale to ask him the problem he had but received no response. racer1320 Mar 28th, 00, 12:08 PM 69, not true. Fits no problem on my 68 with the stock SS hood and I have 1" worth of spacers on the mounting pad. The air gap's mounting pad is actually 1/4" lower than the RPM and the stock drop base air cleaner clears also.

My friend's '70 RS with a 406 performer went from running 12.3 to 11.99 with just that same swap. As for the difference between it and the regular RPM I doubt that there is a noticeable difference BUT it does look a lot cooler and you can route temp sensor wires and vacuum lines underneath the carb for a cleaner look. | ||
